What is anteromedial portal?

What is anteromedial portal?

The independent anteromedial portal technique is thought to better position the femoral tunnel within the native ACL footprint and leave the graft more posteroinferior on the wall of the lateral femoral condyle than the more traditional transtibial approach.

What anatomical structure must the surgeon be aware of while making an anteromedial portal incision?

The anteromedial (AM) portal technique is a popular method to create the femoral tunnel during arthroscopic anterior cruciate ligament (ACL) reconstruction. With this method, one can determine the precise anatomical femoral tunnel position.

What is femoral tunnel position?

Positioning for both femoral tunnel techniques is the same. The patient should be placed in the supine position, with the knee flexed and the foot hanging over the edge of the bed. A tourniquet should be placed as proximally as possible around the thigh, with an arthroscopic leg holder placed directly over this.

What is resident’s Ridge?

The resident’s ridge is arthroscopically identifiable after non-mechanical removal of the soft tissues without bony notchplasty. The ridge is a useful landmark for anatomical femoral tunnel drilling in arthroscopic ACL reconstruction.

How is Blumensaat line measured?

It is calculated by drawing Blumensaat’s line and one line parallel to the distal portion of the ACL. The angle is calculated at the intersection of these two lines. An angle of >15º indicates an abnormal course and probable anterior cruciate ligament tear.

What is ACL tunnel?

Tunnel placement in Anterior Cruciate Ligament (ACL) reconstruction is the single most important variable that a surgeon can control in order to achieve a successful outcome. The femoral tunnel is more critical than the tibial. Audit tunnel positions after ACL reconstruction in a regional centre.

Why is a Notchplasty performed?

Notchplasty is an ancillary surgical procedure that consists of reshaping and widening of the intercondylar femoral notch, historically developed and performed with the aim to avoid ACL graft impingement and improve visualization of the lateral wall of the femoral notch during ACLR surgery.

What is insall Salvati ratio?

Insall–Salvati (IS) ratio is used in measuring the patellar height to detect patellar height abnormalities such as patella alta and patella baja. It is the ratio of the length of the patellar tendon to the maximum length of patella.

What is a patella alta?

Patella alta or high-riding patella refers to an abnormally high patella in relation to the femur. The patella sits high on the femur where the groove is very shallow. Here, the sides of the femoral groove provide only a small barrier to keep the high-riding patella in place.

What is over the top position ACL?

The femoral pass of the graft is performed through the “over the top” position. A femoral tunnel is performed on the lateral supracondylar region in the caudocranial and lateromedial direction. Femoral fixation is achieved using an interference screw. ACL, anterior cruciate ligament.

What is a notch plasty?

Discussion. Notchplasty is an ancillary surgical procedure that consists of reshaping and widening of the intercondylar femoral notch, historically developed and performed with the aim to avoid ACL graft impingement and improve visualization of the lateral wall of the femoral notch during ACLR surgery.

Where is the notch in the knee?

The intercondylar notch is the open space that lies between the medial and lateral femoral condyles of the distal femur and houses the substance of both the anterior and posterior cruciate ligaments.
